Red Bull Sugar Free is made using a carefully selected blend of ingredients that support physical and mental performance without added sugar. The main ingredient is carbonated water, which provides a refreshing fizz. Citric acid is used to balance the flavor with a touch of tartness. Taurine (0.4%) is added to support various physiological functions, including muscular and neurological activity. Caffeine (0.03%) acts as a stimulant to help improve concentration and endurance. The product contains sweeteners—sucralose and acesulfame K—used to provide sweetness without calories. Essential B-group vitamins (niacinamide/B3, pantothenic acid/B5, vitamin B6, and vitamin B12) support normal energy metabolism and help reduce tiredness. Riboflavin and caramel coloring are used to give the drink its characteristic appearance, and natural and artificial flavorings complete the taste profile.

Red Bull Sugar Free 6 x 4 x 250ml contains no allergens as defined by UK and EU regulations. It is gluten-free, lactose-free, and suitable for individuals avoiding genetically modified ingredients. While the drink is generally safe for healthy adults, it is not recommended for children, pregnant or breastfeeding women, or those sensitive to caffeine due to its high caffeine content. As always, consumers with dietary restrictions or medical conditions should review the packaging for the most accurate and up-to-date allergen and ingredient information.
